- To allwhom it'may' concern.

Be it known that we, LEONARD E. HURST and JAMES F. MILLER, citizens of the United States, and residents of Detroit, Wayne County, Michigan, have invented a new and Improved Rail Fastener, of which the fol lowing is a specification.

This invention relates to means for attaching rails and other beams to'theflanges of beams and channels and to other sup ports, and its object is to provide a device of: this character. which will rigidly unite to securethe bolt to the support.

.the rail or other beam to its support, which will'not extend beyond. the edges ofthe base of the rail or other beam, which can be produced asa stock device and is freelyad justable,{'and which can be produced at low cost."

This invention" consists in combination with a flanged rail or other beam and a}. support therefor, of a bolt transversely perforated or otherwise deformed at one end and preferably threaded at .the other, the bolt being adapted to extend through the supportingbeam, channel or other support into a hole drilled into the rail or other beam through thebase and cutting the web thereof, a pin connected to and extending transversely of the bolt above the base of the supported member, and means, preferably a nut, at the opposite end of the bolt It further consists in the details of construction illustrated in the accompanying drawing and particularly pointed out in the claims.

In the drawlng, Fig. 1 is a transverse sec- 7 tion of a conveyer trough'and of the rails for supporting'the conveyer flights. Fig. 2 is a longitudinalsection through the rail fastener. Fig. 3 is a perspective of a lock-' ing pin and Fig. d is a perspectiveof a bolt. Similar reference characters refer to like parts throughout the several views. V

Fig. 1 of the. drawing shows a cross section of a trough having a bottom l on which rest the channel bars 2- whose upper flanges 3 are perforated at intervals to receive bolts 4 whose lower ends are preferably threaded and whose upper ends are perforated or otherwise deformed to receive the transverse pins 5. Therails G'reston the flanges 3 and holes are drilled through the bases 7 of, the rails, preferably along their middle lines, cutting the webs 8 to ad mit the ends of the bolts 4; Pine extend.

punched'cold from sheet metal ithrough the perforationsin the bolts and are of suflicient length to rest on the flanges of the bases of the rails.

As the upper. surfaces of these flange-s slope downwardly and outwardly, I prefer to form the pins to fit these surfaces, their lower sides 10 sloping accordingly to the slopes ofthetop sides of the bases of the rails. This is of advantage, for afterstress is placed on a bolt by its nut 11, it is practically impossible to remove the pin 9. We prefer to place beveled washers 12 and lock washers 14 between the nuts 11 and the inclined lower surfaces of the flanges 3.

The bolts 5L are easily made of any desired lengthand they can be perforated by punching while hot. 'The pins 5 may be of the proper thickness.

,The details of construction and the-proportions of the parts may all be changed by those skilled in the art without departing from the spirit ofour invention as set forth in the following claims.

We claim 1. A fastener comprising a bolt extending into ahole formed in thebase and web flange of the beam and the base and web of .7 the rail are formed with alined holes, a

bolt extending through said hole in the flange of the beam and into the hole in the base and web of the rail, the end of the bolt in the hole in the. rail being transversely perforated, a pin extending across in said perforation and engaging the upper surface of the rall base, and means to secure the bolt to the flange of thebeam.

3. A fastener to secure a. rail to the outer surface of a flange of a beam where the flange of the beam and the base and web of the rail are formed with alined holes, a bolt extending through said hole in the flange of the beam and into the hole in the base andweb of the rail, the end of the bolt in the hole in the rail being transversely perforated, a pin extending across in said perforation and engaging the upper surface of the rail base, and means to secure the bolt to the flange of the beam and embedying a Washentp fit the lower side of-the-flenge of the upport end a nut 0n the belt on the opposite ide 01 the washer from th flange,

4. A fastener te seeu re a rail to the enter surface 'of a flange of a beam Where the flange of the beam and the base and web of' the rail are formed with alined heles, a belt extending through said helein the flange 01 the beam and into the hole in the base and 10 Web ofthe rail, the end of the bolt in the hole in the rail being trensvergely perferated, a pinextending ziere ss infsaldperforation. and engaging the upper surface of the reil-lmse, end meane to eecure thebolt t0 the fiangeefthe bea'ln', 's'ti'id pin having one side inclined in two direetions'to fit the u per surface of the rail base and be held thereby. in said pe fomtion in the bolt.
